8 Claims. (01. 97-4981) This invention aims to provide novel meanswhereby soil-engaging elements "may be assembled with the beams of acultivator, in adjusted positions. i

It is within the province of the disclosure t improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in View, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention 'herein disclosed, may be made within thescope of what is claimed, without departing from the spirit oftheinverition.

In the accompanying drawings:

Fig. 6 is an end view of the structure depicted in Fig. 5;

Fig. '7 is a top plan of the structure shown in Figs. 5 and 6; 1 I

Fig. 8 is an enlarged sectional view showing a portion of the structureappearing in Figs. 5, 6 and '7; v

Fig. 9 is a perspective view showing the supplemental beam.

In Figs. 1 and 2, cultivator beams are shown at l. Hangers 2 areprovided, and each hanger includes a first arm 3 and a second arm 4arranged at right angles to the first arm 3, the hangers 2 beingtwisted, as shown at 5, at the juncture between the arms 3 and 4, sothat, so far as major transverse dimensions are concerned, the arms 3and 4 are in planes at right angles to each other. The hangers 2 neednot be of the precise construction shown and described, especially as tothe twist shown at 5, and the hangers may be of any preferred form inwhich the general rectangular relation between the arms 3 and 4 issubstantially preserved. By means of clips 6 and securing elements I,the first arms 3 of the hangers 2 are secured for vertical adjustment tothe cultivator beams I.

Brackets are provided, and one of the brackets disclosing, one of v 5.2:is shownin Fig. 3, the bracket being designated by the numeral 8. Eachbracket comprises a first or vertical depending flange 9 and a second orhorizontal flange Ill. The flanges 10 of 1 the brackets Son therespectivebeams project out- 3 wardly in opposite directions withrespect to the median plane of the implement. There are spaced lines ofopenings H in the flange 9, and spaced lines of openings l2 in theflange It]. By means of securing elements [4, mounted in one I) of thelines of openings I2, the second or horizontal arms 4 of the hangers 2are connected to the second or" horizontal. flanges H] of the brackets8. Securing elements I5, mounted in any k one of the lines of openingsI2, attach the hori- 15 zontal shanks iii of soil-engaging elements I!to the flanges N3 of the brackets 8. The securing elements I5 may bemounted in any of the lines of openingsiZ, and, thus, a horizontaladjustment between the soil-engaging elements I! may be r20 broughtabout, A vertical adjustment may be secured by shifting the first arms 3of the hangers 2 in the clips 6. Figures 1 and 2 show one of thesimplest applications of the'invention.

In Fig. 4, parts hereinbefore described have: been designated bynumerals previously used, with the suffix a. The flangesv Illa of thebrackets 8a of the respective beams la project inwardly with respect tothe median plane'- of the implement. Brackets I 8, constructed like thebrackets 8 are provided. The vertical arms I!) of the brackets i8,corresponding to the arms 9a, are attached tothe arms 9a by securingelements 20. The arms or flanges 2| ,of the brackets l8 extendoutwardly, and to them the shanks of soil-engaging elements 22 aresecured, as shown at 23, by means of bolts or the like, mounted in theopenings corresponding to the openings l2 of Fig. 3. ,It will beobserved that an in and out horizontal adjustment of the soil-engagingelements 22 is possible. The arms 3a. of the hangers nearest to themedian plane of the implement are caused to extend upwardly instead ofdownwardly and the arrangement of parts is such that the soil-engagingelement can work upon a ridge 24 of considerable height.

In Figs, 5, 6 and 7, parts hereinbefore described have been designatedby numerals already used, with the suffix b.

In this arrangement, the brackets IBb, corresponding to the brackets lBaare used, but they extend upwardly, instead of downwardly as in Fig. 4.

Extension bars 25 are provided and have countersunk openings 26 adaptedto receive secur 55 ing elements 2'! which attach the extension bars tothe flanges lb and 2lb of the brackets 8b and IE1) respectively. Theextension bars 25 may project either rearwardly or forwardly, as shownin Fig. '7, and the shanks 28 of the soil-engaging elements 29 areoverlapped upon the extension bars 25 and are attached thereto bysecuring elements 30. Because the extension bars 25 may be made toproject either forwardly or rearwardly, the soil-engaging elements 29may be spaced apart, longitudinally of the draft line, the extensionbars 25 having openings 3! for the reception of the securing elements3!]. A transverse adjustment of the soil-engaging elements 29 also isprovided, owing to the presence of the lines of openings 12b in theflanges 21b and lllb of the brackets 8b and 181) respectively.

It will be observed that numerous horizontal and vertical adjustmentsare possible in the positions of the soil-engaging elements, thearrangement of parts shown in Fig. 6 being of peculiar utility whenthesoil-engaging elements 29 must work in a hollow, the soil-engagingelements 22 of Fig. 4 being adapted to work on a ridge, and thesoil-engagmg elements H of Fig. 2 being adapted to work on comparativelylevel ground.

What is claimed is:

1. In a device of the class described, a hanger comprising horizontaland vertical arms, means for securing the vertical arm to a plow beamfor vertical adjustment, a bracket having recvtangularly disposed parts,means for attaching one of the rectangularly disposed parts of thebracket to the horizontal arm of the hanger, a soil-engaging element,and means for'attaching the soil-engaging element to one of therectangularly disposed parts of the bracket.

2. In a device of the class described, a hanger having a vertical armand a horizontal arm, a bracket having rectangularly disposed parts, a

securing member joining one part of the bracket to the horizontal arm ofthe hanger, a soil engaging element, and means for connecting thesoil-engaging element to one of said parts of the bracket.

. 3. A device of the class described, constructed as set forth in claim2, and wherein the substantially horizontal part of the bracket hastransversely spaced openings for the reception of the securing member.

4. A device of the class described, constructed as set forth in claim 2,and wherein said means comprises a securing member connecting thesoilengaging element to the substantially horizontal part of thebracket.

5. A device of the class described, constructed as set forth in claim 2,and wherein said means comprises a securing member connecting thesoilengaging element to the substantially horizontal part of thebracket, said part having transversely spaced openings for theadjustable reception of the last-specified securing member.

6. In a device of the class, described, a hanger having an upstandingarm and a substantially horizontal arm, a first bracket having adependingpart and an inwardly extended substantially horizontal part, 'asecuring member joining the substantially horizontal part of the bracketto the substantially horizontal arm of the hanger, a second bracketconstructed like the first bracket, but in-verted to comprise anupstanding part and an outwardly extended part, a securing memberjoining the depending part of the first bracket with the upstanding partof the second bracket, a soil-engaging element, and means for securingthe soil-engaging element to the outwardly extended part of the. secondbracket.

7. In a device of the class described, upper and lower brackets, eachcomprising a horizontal part and a vertical part, means for connectingthe vertical parts of the brackets together to permit an inversion ofthe lower bracket, thereby to disposethe horizontal part of the lowerbracket higher than or lower than the horizontal part of. the upperbracket, atthe will of an operator, soil-engaging elements, and meansfor securing-one soil-engaging element to thehorizontal part of eachbracket.

8. A device of the class described, constructed as set 'forth in claim 7and wherein the lastspecified means embodies, extension bars whereon thesoil-engaging elements are mounted, and means for securing the extensionbars to the horizontal parts of the brackets, with one extension barprojecting forwardly and the other extension bar projecting rearwardly,thereby to space the soil-engaging elements apart, longitudinally of theline of advance of the soil-engaging elements.
